Abstract
The present invention relates to a hole-free squeezed reveted member and its making method. It is characterized by that on its first combination block several holes are set, the top of the hole is equiopped with an inverted groove, on its second combination block several projections are set, the top of the projection is equiopped with on inverted groove, the projections on the second combination block and the holes on the first combination block are tightly fit, so that the first combination block and second combination block can be reveted together by means of material squeezing principle.
Description
Technical field:
The invention relates to Holeless extruded-riveted piece and manufacture method thereof, needing can be used for the various fields of two combined blocks of riveted, in particular for the riveted between the shell fragment.
Background technology:
When needing to carry out riveted between two combined blocks, need be with certain riveted mode with its riveted, existing now multiple riveted mode, as the riveted that sprouts, two direct riveteds, blind rivet riveted etc.
The riveted that sprouts is to make a call to an aperture on first combined block, and a groove is arranged on second combined block, and the hole is corresponding with groove, utilizes a pressurizing unit that the material around the hole on first combined block is expressed in the groove of second combined block, thereby carries out riveted.But this kind riveted mode can stay a hole at extrusion position, easily produces problem of rustiness.
Two direct riveteds are directly first combined block and second combined block to be put together, push, the molecule of first combined block and the second combined block molecule interpenetrate, thereby carry out riveted, but this kind riveted mode can make material production pultrusion phenomenon, influences the flatness of combined block.
Can not be porose or flatness require very tight occasion, above-mentioned two kinds of riveted modes do not reach requirement.
The blind rivet riveted is by pulling out a spike thing first combined block and second combined block to be combined, and carries out riveted, but this kind riveted mode blind rivet expense height, manufacturing process is slower, and the production cycle is long.
In view of the shortcoming of above-mentioned various riveted modes, the inventor works out Holeless extruded-riveted piece and manufacture method thereof, utilizes this Holeless extruded-riveted, can reduce expense, shortens process cycle, and can not stay aperture and produce material pultrusion phenomenon.
Summary of the invention:
The present invention's main purpose provides a Holeless extruded-riveted piece, and the hole of groove of band is arranged on first combined block, and the projection of groove of band is arranged on second combined block, and projection and hole closely cooperate, thereby with two combined block riveteds.
Another main purpose of the present invention provides a Holeless extruded-riveted method, the projection of passing the first combined block hole is arranged on second combined block, the outer dia of projection is identical with the diameter in hole, the upper end material of projection is expressed to the groove that falls in hole, make the top of second combined block also become a structure of falling the groove, thereby with two combined block riveteds.
Another object of the present invention provides a Holeless extruded-riveted method, the upper end material of the second combined block upper process is expressed in the groove of first combined block, can not produce extruded hole, and material can not be out of shape, for can not be porose or the combined block flatness require very tight occasion, also can reach requirement.Because atresia just can not produce the problem of getting rusty yet.
The present invention's a purpose again provides a Holeless extruded-riveted method, only need the upper end of the second combined block upper process be pressed to put to flush with end on first combined block with drift to get final product in the process of operation, and manufacturing process is rapid, has shortened the production cycle.

Fig. 1 is the partial sectional view of the present invention's first combined block;
Fig. 2 is the partial sectional view of the present invention's second combined block;
Fig. 3 for the present invention's first combined block and second combined block not the broken section during riveted in conjunction with figure;
Cutaway view when Fig. 4 pushes for the present invention;
Specific embodiment:
Present embodiment is mainly used in the riveted of computer housing inner shrapnel, and several holes 11 are as shown in Figure 1 wherein arranged on the combined block 1, and the top in hole 11 has one to fall groove 12, and the top diameter of groove 12 of falling is big, below diameter little.
Several column type projections 21 (as Fig. 2) are arranged on the combined block 2, the position in the hole 11 on column type projection 21 and the combined block 1 is corresponding, more than half part is a hollow below the projection 21, its wall has certain thickness, hole 11 equal diameters on the outer dia of column type projection 21 and the combined block 1, the height (as shown in Figure 3) in a little higher than hole 11 of the height of column type projection 21.
During the invention process, combined block 1 and combined block 2 are put together, as shown in Figure 3, place it on the counterdie 4 (as shown in Figure 4), with a drift 3 column type projection 21 on the combined block 2 is higher than the part of combined block 1 to pressing down, the material on the top of column type projection 21 is expressed to falling in the groove 12 of hole 11, be that the top of projection 21 also forms one and falls groove 22 (as shown in Figure 4), and the upper surface flush that makes column type projection 21 is in the upper surface of combined block 1, promptly this moment the height of cylindrical projections 21 and hole 11 height equate that the height of groove 12 of falling on the projection 21 to fall on the height of groove 22 and the hole 11 equates.
So invention can realize the riveted between two combined blocks thus, owing to be that column type projection 21 outstanding a part of materials are expressed in the groove 12 in hole 11, so the phenomenon that the center of circle is porose or the generation material pushes can not occur, for can not be porose or flatness require very tight occasion, also can reach requirement, operating process is simple, makes manufacturing process rapider, has shortened the manufacturing cycle.
The above only is the present invention's preferred embodiment, the interest field that the present invention advocated; be not limited in this, by all personages who is familiar with this technology, according to the technology contents that the present invention disclosed; can think easily and equivalent transformation, the protection domain that all should not break away from the present invention.
